Abstract Background Bile duct injury and vasculobiliary injury are possible complications during laparoscopic cholecystectomy which can lead to increased morbidity, mortality, costs of hospitalization and litigation. Proper documentation of the critical view of safety and safe plane of dissection may play a crucial role for archivization, teaching and medicolegal purposes. Methods The study group consisted of 100 patients with symptomatic cholecystolithiasis qualified for laparoscopic cholecystectomy. The critical view of safety was documented on two photographs and safe plain of dissection obtained with laparoscopic ultrasound was documented on one photograph as well as the whole procedure was recorded. The photographs were printed in the operating theatre and videos were stored on an external hard drive. Results The mean time to obtain and analyse photographs was significantly shorter than video, and the size of the stored data was significantly smaller for photographs than videos. The cost of one documentation procedure was significantly lower for video than photographs. Critical view of safety was obtained in 91 patients, and laparoscopic ultrasound was successful in 99 patients. The conversion rate was 2%, and fundus-first cholecystectomies were performed in 6% of patients. We did not observe any biliary and vascular complications. Conclusions Photographic documentation of the critical view of safety and safe plane of dissection should be an inherent part of laparoscopic cholecystectomy. Our proposal of documentation prepared in the operating theatre and stored in the patient’s documentation is an example of an easy, fast and cheap method of data archivization.

Full textAbstract:
The work of an Austrian artist Lukas Birk can be connected to some dilemmas of documentary photography. If the critique of the classical documentary photography stresses the responsibility towards the photographed subject and the problem of the exoticization for the western view, Birk’s work is often developed, displayed and distributed in the place where his projects are created. Therefore, the first audience of his projects are locals and are, in that way, maybe more closely connected to the project itself. He co-founded the Austro Sino Arts Program in China and founded a residency program SewonArtSpace in Yogyakarta, Indonesia. The project Afghan Box Camera, which he developed with the ethnographer Sean Folley, focuses on the photographic praxis in Afghanistan, mainly on the type of a simple instant camera, which was traditionally used there but its use is now in decline. They investigated the origins, techniques and the many personal stories of the photographers using or having used this type of camera and also made instructional videos on how to build or use one. Attention to the overlooked photographic practices, history and contexts marks also his current project The Myanmar Photo Archive, a growing collection of Myanmar photographs that were created during and after the colonial period – the work of local photographers from that period has namely remained unknown until today. Keywords: local history, Myanmar photography, photographic backdrop, western view

ABSTRACTUse of smartphone has become ubiquitous. With smartphone cameras becoming powerful, they are replacing digital cameras and digital SLRs as primary instruments to take photos and record videos. It is natural even for plastic surgeons that smartphones are handy to take still photographs and even record high-definition or 4K videos. Another invention which has become popular with smartphone photography is a selfie stick. We explain the possibility and methodology of using an iPhone and selfie stick to take operative photographs and high-quality videos.

Full textAbstract:
AbstractThe canine photographs, videos, and photographic narratives of artist William Wegman frame questions of animal aesthetic agency. Over the past 30 years, Wegman's dog images shift in form and content in ways that reflect the artist's increasing anxiety over his control of the art-making process once he becomes identified, in his own words, as "the dog photographer". Wegman's dog images claim unique cultural prominence, appearing regularly in fine art museums as well as on broadcast television. But, as Wegman comes to use these images to document his own transition from dog photographer to dog breeder, these texts also reflect increasing restrictions on what I term the "pack aesthetics," or collaborative production of art and artistic agency, that distinguish some of the early pieces. Accounting for the correlations between multiple and mongrel dogs in Wegman's experimental video work and exclusively Weimaraner-breed dogs with human bodies in his recent work in large-format Polaroid photography, this article explores how Wegman's work with his "video dog star," his first Weimaraner dog Man Ray, troubles the erasure of the animal in contemporary conceptions of artistic authority.

Full textAbstract:
✓ The authors examine the quality of intraoperative photography in which digital recording technology, including a microdigital camera and digital video paired with an operating microscope, is used during neurosurgery. A microdigital camera developed for this purpose (1.4 million pixels) was attached to an operating microscope and used during surgery. The same surgical views with precisely the same optical conditions were taken through the microscope by using both a conventional 35-mm camera and the microdigital camera, and the quality of the final output was compared. In addition, the quality of the digital camera photographs was compared with the still photograph clipped from the digital video recording.The quality of the photographs taken with a microdigital camera was superior to the quality of those obtained with the conventional 35-mm camera. The success rate of recording (what you see is what you get) was almost 100%. The quality of the still photographs clipped from the digital video was nearly equal to those taken with the digital camera. The microdigital camera system is superior to the conventional 35-mm camera in neurosurgery in terms of its success rate and the quality of the photography. It is also a space-saving system for storing the huge amount of data generated in the recording of surgical procedures, and the cost/performance ratio is superior to that of the conventional method. Digital technology including digital cameras and videos is very useful for clear recording of microsurgical procedures.

Full textAbstract:
The difficulty in precisely detecting and locating an ear within an image is the first step to tackle in an ear-based biometric recognition system, a challenge which increases in difficulty when working with variable photographic conditions. This is in part due to the irregular shapes of human ears, but also because of variable lighting conditions and the ever changing profile shape of an ear’s projection when photographed. An ear detection system involving multiple convolutional neural networks and a detection grouping algorithm is proposed to identify the presence and location of an ear in a given input image. The proposed method matches the performance of other methods when analyzed against clean and purpose-shot photographs, reaching an accuracy of upwards of 98%, but clearly outperforms them with a rate of over 86% when the system is subjected to non-cooperative natural images where the subject appears in challenging orientations and photographic conditions.

Historical archives save invaluable treasures and play a critical role in the conservation of Cultural Heritage. Old photographs and videos, which have survived over time and stored in these archives, preserve traces of architecture and urban transformation and, in many cases, are the only evidence of buildings that no longer exist. They are a precious source of enormous informative potential in Cultural Heritage documentation and save invaluable treasures. Thanks to photogrammetric techniques it is possible to extract metric information from these sources useful for 3D virtual reconstructions of monuments and historic buildings. This paper explores the ways to search for, classify and group historical data by considering their possible use in metric documentation and aims to provide an overview of criticality and open issues of the methodologies that could be used to process these data. A practical example is described and presented as a case study. The video “Torino 1928”, an old movie dating from the 1930s, was processed for reconstructing the temporary pavilions of the “Exposition” held in Turin in 1928. Despite the initial concerns relating to processing this kind of data, the experimental methodology used in this research has allowed to reach a quality of results of acceptable standard.

The YouTube platform hosts a multitude of video clips that contain various media representations of the collective memory of Soviet history. In this array of multimedia products, videos created by ordinary bloggers take their own place. Videos with themes about the recent Past are formed on the basis of digitized fragments of documentary and fiction films, photographs, posters, postcards, drawings, etc. Verbal comments of viewers-users to videos expand and change their semantic content. The purpose of the article is to reveal in the videos of ordinary bloggers various techniques for audiovisual constructing the collective memory of the mass repression of the 1930s and the Gulag. The criteria for selecting sources for the study are: the time they were posted on the YouTube platform (2010s), video bloggers claim to be documentary, the number of comments. The research results demonstrate that bloggers shape clusters of collective memory of the repressions and the Gulag using audiovisual signs and symbols that are easily recognizable by viewers. The same photographs and film fragments can “work” in video differently depending on how they relate to the verbal and audio components of multimodal text. The techniques used by bloggers for audiovisual documentation of the Soviet Past combine pre-digital and digital technologies. The selection of certain audiovisual components as “raw data” for video, their montage, giving historical figures certain roles, organizing time and space in a digital narrative, including different social and political contexts in it, all allow bloggers to form various representations of the collective memory of the Soviet past, depending on their ideological positions.

Physical objects, phenomena, laws and theories are studied in high school physics. They can be presented through various visual aids such as experiments, diagrams, graphics, photographs, videos and more. Our focus is on educational photographs as a means of visualizing physical objects and phenomena. Educational photographs’ merits are presented. They can be used in all types of physics lessons. For example, lessons for new knowledge or solving problems, laboratory or seminar lesson. Important didactic functions that they perform are considered such as illustrating of physical objects, technical application of studied laws and phenomena, solving problems during the lesson or for independent work and creating problematic situations. The emphasis is on the so-called photo tasks, which solution can be realized with the help of an interactive whiteboard. The use of digital photography in physical educational experiment is also considered. A model of the activity of the teacher and the students in conducting physics laboratory work is proposed. A methodology for using digital photography in physics demonstration experiment is presented.

With each passing day resolutions of still image/video cameras are on the rise. This amelioration in resolutions has the potential to extract useful information on the view opposite the photographed subjects from their reflecting parts. Especially important is the idea to capture images formed on the eyes of photographed people and animals. The motivation behind this research is to explore the forensic importance of the images/videos to especially analyze the reflections of the background of the camera. This analysis may include extraction/ detection/recognition of the objects in front of the subjects but on the back of the camera. In the national context such videos/photographs are not rare and, specifically speaking, an abductee’s video footage at a good resolution may give some important clues to the identity of the person who kidnapped him/her. Our aim would be to extract visual information formed in human eyes from still images as well as from video clips. After extraction, our next task would be to recognize the extracted visual information. Initially our experiments would be limited on characters’ extraction and recognition, including characters of different styles and font sizes (computerized) as well as hand written. Although varieties of Optical Character Recognition (OCR) tools are available for characters’ extraction and recognition but, the problem is that they only provide results for clear images (zoomed).

Digital video technologies are new and powerful tools with wide applications in orthopedic. Already integral to several common medical devices, digital images can be used for case documentation and presentation as well for diagnostic and surgical patient care information. Digital technologies allow easy manipulation of photographic, video and graphic materials in ways that were impossible with conventional techniques. Educational presentation has been transformed by use of computers and digital projectors. Understanding the basic foundations of digital imaging technology is important for effectively creating digital images, videos and presentations. In this review, we are going to discuss some of the issues that are raised by digital imaging in orthopedics, digital image processing, as well as, we are giving some recommendations for good quality of pre-, post- and intra-operative photographs in clinical use.

Abstract Public service, ethics, objectivity, autonomy and immediacy are still often considered the core values of professional journalism. However, photojournalistic work has confronted historic changes since the advent of digitalization in the late 1980s. Professional photo-journalists have been caught manipulating news images, video production has become a major part of news photographers’ work, and newspapers freely publish photographs and videos taken by the general public. The present article examines how news photographers negotiate these changes in photo-journalistic work practices, and how they define their professional ambitions in the digital age. Photojournalists’ articulations of professionalism are approached in relation to three digital innovations in photojournalism: digital photo editing, video production and user-generated images in newspapers. The empirical data consist of an online survey of and interviews with photojournalists in Finland. In the final analysis, it is suggested that the core ideals of photojournalism have to be renegotiated, because the work environment has changed drastically.

160 undergraduate students were given a set of 10 photographs or 10 videotaped recordings of women and informed that some of the women were victims of spousal abuse. Half of the participants were asked to select one individual who seemed most likely or least likely to be a battered woman. Participants then sorted another set of photographs or videos of 10 other battered and nonbattered women into the categories according to their guessed status. Analysis showed that certain women were consistently chosen as exemplars of battered or nonbattered women. Categorizations did not correspond with the women's actual status. No reliable differences in category selections or sotrings were found between photographed and videotaped presentations of the battered and nonbattered women.

Content-based image retrieval is quickly becoming the most common method of searching vast databases for images, giving researchers a lot of room to develop new techniques and systems. Likewise, another common application in the field of computer vision is content-based visual information retrieval. For image and video retrieval, text-based search and Web-based image reranking have been the most common methods. Though Content Based Video Systems have improved in accuracy over time, they still fall short in interactive search. The use of these approaches has exposed shortcomings such as noisy data and inaccuracy, which often result in the showing of irrelevant images or videos. The authors of the proposed study integrate image and visual data to improve the precision of the retrieved results for both photographs and videos. In response to a user's query, this study investigates alternative ways for fetching high-quality photos and related videos.

Tables, graphs, and photographs can effectively convey detailed results of a PGR experiment. However, we have observed that demonstrating PGR treatment effects by time-lapse video creates a strong impact on both scientists and non-technical audiences. Time-lapse video also provides a method for obtaining a continuous visual record that can be used to establish the precise chronology of a slow process. Recent advances in notebook computers, inexpensive digital cameras (e.g. 3Com HomeConnect™), and time-lapse software (e.g. Picture WorkLive™) allow scientists and teachers to inexpensively prepare time-lapse videos. Important considerations for the production of quality time-lapse videos include: 1. treatment effects should be substantial, consistent, and visible, 2. digital camera images should be clear, 3. lighting should be constant and provide adequate brightness and proper color, 4. camera movement such as those due to vibrations should be minimal, 5. camera placement should simplify composition. Time-lapse videos of PGR treatment effects will be shown, and methods of production will be discussed.

Full textAbstract:
This study shows the importance of landscape scene composition in relation to aesthetic ratings used in preference research where static and dynamic presentation methods substitute landscape onsite evaluation. We aimed to evaluate whether the method of presenting a landscape scene influenced aesthetic ratings and whether these potential differences in ratings were affected by the composition of the static presentation. Using a questionnaire for rating the same scenes of agricultural landscapes presented both in photographs and in videos, it was determined that the presentation method used significantly affected ratings. Respondents ( N = 145, age 20-25 years, students) rated scenes presented in photographs higher than videos. Concerning the effect of composition, well-composed photographs had higher mean ratings than poorly composed photographs. Moreover, the difference in ratings between static and dynamic presentation methods determined for well-composed scenes was larger than that for poorly composed scenes, always in favor of photographs. The results indicate that preference ratings can be influenced both by the medium and by composition. This is a crucial aspect for environmental assessments using a visual preference approach as part of planning and management strategies, and it should always be taken into account.

Visuals – images – are a globally understandable exchange and copyable transmission of information. “O God, I could be bounded in a nutshell and count myself a king of infinite space,” Hamlet noticed. We also use our Coronavirus home office for experimental journeys in the Renaissance and Baroque periods. As in the 15th / 16th / 17th Century, worlds far away from us were discovered, and we embark on digital adventures that are temporary, simultaneous, synchronous, asynchronous, independent of location. We decided to work with digital photography as a visual method for mainly two reasons. First, taking photos can be done relatively easy during a shut down in the home office. We can train creativity and visual perception without being in a university's studio. Second, photographs can be analyzed and compared with paintings and therefore criticized by their motifs, aesthetic representation, and within their time frame. Our visual souvenirs are photographs and videos in the mirror of illusion, immersion, and imagination

Full textAbstract:
Previous studies have demonstrated that the angle of women’s lumbar curvature affects men’s attractiveness judgments of them. The theoretically optimal angle of lumbar curvature provides better resistance against both hyperlordosis and hypolordosis as biomechanical costs of a bipedal fetal load that could impair a woman’s fertility. Since men find this attribute attractive, women aim to emphasize it by wearing high-heeled shoes. The primary objective of the present study was to test this evolutionary hypothesis using short videos presenting women walking by the camera. In line with previous findings based on static stimuli (photographs), dynamic stimuli (videos) presenting women walking in high-heeled shoes were expected to elicit increased attractiveness ratings as compared to women wearing flat shoes, which would be associated with the angle of lumbar curvature. Videos were taken of 52 female models walking in two conditions (i.e., wearing either high-heeled or flat shoes). A total of 108 participants (61 males, 47 females) rated the walking models’ physical attractiveness in an online setting. Each model’s lumbar curvature was measured both in high heels and in flat shoes using photographs taken of them prior to each video recording. The results showed that wearing high heels consistently increased the models’ attractiveness, regardless of whether or not it decreased their natural difference from the theoretically optimal angle of lumbar curvature. Both male and female observers showed this positive effect. Furthermore, a negative correlation was found between the models’ body mass index (BMI) and their perceived attractiveness scores in both conditions.

Recent developments in computer vision are seen as a vital advancement in video surveillance. The goal of this research is to build a deep learning model that is capable of analyzing and classifying the video from running CCTV streams to detect criminal actions and identify suspects on the scene. In particular, we focus on the detection of dangerous human behaviors in surveillance videos. This work provides a low cost embedded solution that can be integrated with the existing CCTV cameras. This integration can reduce the cost of transmitting the data to any centralized server, which may have various privacy implications and takes much inference time. We also benchmark our models performance with the existing real-world dataset in terms of accuracy and resource constraints. Using the concept of Multiple Instance Learning on the histogram of the optical flow of the videos combined with the pose estimation of the persons on scene, we provide a lightweight model which has 13 times lesser inference time than the existing very deep models. Focusing on one important thing, this research will expand to which state-of-the-art deep neural networks will “see” violence in photographs and videos, and recognize criminal behavior using characteristics such as gestures, gait, and unethical behavior. This helps enforcement agencies to unravel crime cases faster and also to scale back crimes by identifying the suspects in the surveillance videos.

Full textAbstract:
There is substantial archival data available in different forms, including manuscripts, printed papers, photographs, videos, audios, artefacts, sculptures, building, and others. Media content like photographs, audios, and videos are crucial content because such content conveys information well. The digital version of such media data is essential as it can be shared easily, available in the online or offline platform, easy to copy, easy to transport, easy to back up and easy to keep multiple copies at different places. The limitation of the digital version of media data is the lack of searchability as it hardly has any text that can be processed for OCR. These important data cannot be analysed and, therefore, cannot be used in a meaningful way. To make this data meaningful, one has to manually identify people in the images and tag them to create metadata. Most of the photographs were possible to search based on very basic metadata. This data, when hosted on the web platform, searching media data is becoming a challenge due to its data formats. Improvement in existing search functionality is required to improve the searchability of the photographs in terms of ease of usage, quick retrieval and efficiency. The recent revolution in machine learning, deep learning and artificial intelligence offers a variety of facilities to process media data and identify meaningful information out of it. This research paper explains the methods to process digital photographs to classify people in the given photographs, tag them and saves that information in the metadata. We will tune various hyperparameter to improve their accuracy. Machine learning, deep learning and artificial intelligence offers several benefits, including auto-identification of people, auto-tagging them, provide insights and finally, the most important part is it improves the searchability of photographs drastically.
It was envisaged that about 85% of the manual tagging activity might be reduced and improves the searchability of photographs by 90%.

Full textAbstract:
Investigating human consciousness based on brain activity alone is a key challenge in cognitive neuroscience. One of its central facets, the ability to form autobiographical memories, has been investigated through several fMRI studies that have revealed a pattern of activity across a network of frontal, parietal, and medial temporal lobe regions when participants view personal photographs, as opposed to when they view photographs from someone else’s life. Here, our goal was to attempt to decode when participants were re-experiencing an entire event, captured on video from a first-person perspective, relative to a very similar event experienced by someone else. Participants were asked to sit passively in a wheelchair while a researcher pushed them around a local mall. A small wearable camera was mounted on each participant, in order to capture autobiographical videos of the visit from a first-person perspective. One week later, participants were scanned while they passively viewed different categories of videos; some were autobiographical, while others were not. A machine-learning model was able to successfully classify the video categories above chance, both within and across participants, suggesting that there is a shared mechanism differentiating autobiographical experiences from non-autobiographical ones. Moreover, the classifier brain maps revealed that the fronto-parietal network, mid-temporal regions and extrastriate cortex were critical for differentiating between autobiographical and non-autobiographical memories. We argue that this novel paradigm captures the true nature of autobiographical memories, and is well suited to patients (e.g., with brain injuries) who may be unable to respond reliably to traditional experimental stimuli.

Full textAbstract:
The article is focused on advantages of using visual methods in qualitative psychological research of personality. The visual turn is not new for the social sciences. Still, this trend is relatively new for psychology. Currently, visual forms of communication have significantly expanded their influence in all areas of culture. This change has led to a rethinking of the strategy of using various visual data in psychological research. In modern qualitative research, visual data is represented by a variety of cultural instruments, from maps, diagrams and matrices, to photographs, videos, collages and drawings. A comprehensive analysis of this problem requires a multimodal approach, representing a combination of different types of communication (audio, visual, textual) and corresponding types of data (spoken words, music, sounds, written words, images, photographs, maps, videos, etc.). This approach lets us set new research tasks and explore new areas, e.g. emotional and bodily components of personal experience and personal changes. The expansion of the scope of visual methods should positively influence the researcher's ethical choices.

Full textAbstract:
Feral cats (Felis catus) have long been implicated as nest predators of endangered ‘Ua‘u (Hawaiian Petrel; Pterodroma sandwichensis) on Hawai‘i Island, but until recently, visual confirmation has been limited by available technology. ‘Ua‘u nest out of view, deep inside small cavities, on alpine lava flows. During the breeding seasons of 2007 and 2008, we monitored known burrows within Hawai‘i Volcanoes National Park. Digital infrared video cameras assisted in determining the breeding behaviour and nesting success at the most isolated of burrows. With 7 cameras, we collected a total of 819 videos and 89 still photographs of adult and nestling ‘Ua‘u at 14 burrows. Videos also confirmed the presence of rats (Rattus spp.) at 2 burrows, ‘Ôma‘o (Myadestes obscurus) at 8 burrows, and feral cats at 6 burrows. A sequence of videos showed a feral cat taking a downy ‘Ua‘u chick from its burrow, representing the first direct evidence of ‘Ua‘u depredation by feral cat in Hawai‘i. This technique provides greater understanding of feral cat behaviour in ‘Ua’u colonies, which may assist in the development of more targeted management strategies to reduce nest predation on endangered insular bird species.

AbstractObjectiveTo examine the acceptability and feasibility of using smartphone technology to assess beverage intake and evaluate whether the feasibility of smartphone use is greater among key sub-populations.DesignAn acceptability and feasibility study of recording the video dietary record, the acceptability of the ecological momentary assessment (EMA), wearing smartphones and whether the videos helped participants recall intake after a cross-over validation study.SettingRural and urban area in Shanghai, China.SubjectsHealthy adults (n 110) aged 20–40 years old.ResultsMost participants reported that the phone was acceptable in most aspects, including that videos were easy to use (70 %), helped with recalls (77 %), EMA reminders helped them record intake (75 %) and apps were easy to understand (85 %). However, 49 % of the participants reported that they had trouble remembering to take videos of the beverages before consumption or 46 % felt embarrassed taking videos in front of others. Moreover, 72 % reported that the EMA reminders affected their consumption. When assessing overall acceptability of using smartphones, 72 % of the participants were favourable responders. There were no statistically significant differences in overall acceptability for overweight v. normal-weight participants or for rural v. urban residents. However, we did find that the overall acceptability was higher for males (81 %) than females (61 %, P=0·017).ConclusionsOur study did not find smartphone technology helped with dietary assessments in a Chinese population. However, simpler approaches, such as using photographs instead of videos, may be more feasible for enhancing 24 h dietary recalls.

Abstract Most studies on facial attractiveness have relied on attractiveness judged from photographs rather than video clips. Only a few studies combined images and video sequences as stimuli. In order to determine static and dynamic cues to male attractiveness, we perform behavioural and computational analyses of the Mr. World 2014 contestants. We asked 365 participants to assess the attractiveness of images or video sequences (thin slices) taken from the profile videos of the Mr. World 2014 contestants. Each participant rated the attractiveness on a 7-point scale, ranging from very unattractive to very attractive. In addition, we performed computational analyses of the landmark representations of faces in images and videos to determine which types of static and dynamic facial information predict the attractiveness ratings. The behavioural study revealed that: (1) the attractiveness assessments of images and video sequences are highly correlated, and (2) the attractiveness assessment of videos was on average 0:25 point above that of images. The computational study showed (i) that for images and video sequence, three established measures of attractiveness correlate with attractiveness, and (ii) mouth movements correlate negatively with attractiveness ratings. The conclusion of the study is that thin slices of dynamical facial expressions contribute to the attractiveness of males in two ways: (i) in a positive way and (ii) in a negative way. The positive contribution is that presenting a male face in a dynamic way leads to a slight increase in attractiveness rating. The negative contribution is that mouth movements correlate negatively with attractiveness ratings.

Full textAbstract:
Purpose. We describe in detail a relatively simple technique of fundus photography in human and rabbit eyes using a smartphone, an inexpensive app for the smartphone, and instruments that are readily available in an ophthalmic practice.Methods. Fundus images were captured with a smartphone and a 20D lens with or without a Koeppe lens. By using the coaxial light source of the phone, this system works as an indirect ophthalmoscope that creates a digital image of the fundus. The application whose software allows for independent control of focus, exposure, and light intensity during video filming was used. With this app, we recorded high-definition videos of the fundus and subsequently extracted high-quality, still images from the video clip.Results. The described technique of smartphone fundus photography was able to capture excellent high-quality fundus images in both children under anesthesia and in awake adults. Excellent images were acquired with the 20D lens alone in the clinic, and the addition of the Koeppe lens in the operating room resulted in the best quality images. Successful photodocumentation of rabbit fundus was achieved in control and experimental eyes.Conclusion. The currently described system was able to take consistently high-quality fundus photographs in patients and in animals using readily available instruments that are portable with simple power sources. It is relatively simple to master, is relatively inexpensive, and can take advantage of the expanding mobile-telephone networks for telemedicine.

In this operative video atlas manuscript, the authors demonstrate the operative nuances and surgical technique for endoscopic-assisted microvascular decompression of a large ectatic vertebral artery causing hemifacial spasm. A retrosigmoid approach was performed and a large ectatic vertebral artery was transposed away from the root exit zone of cranial nerve VII (Fig. 1). The lateral spread response disappeared, signifying adequate decompression of the facial nerve (Fig. 2). The use of endoscopic-assistance during the microsurgical decompression was very useful to confirm the origin and also the resolution of neurovascular conflict. Postoperatively, the patient experienced immediate resolution of hemifacial spasm with normal facial nerve and hearing function. Written consent was obtained from the patient to publish videos, photographs, and images from the surgery.The link to the video can be found at: https://youtu.be/RlMz44uCDCw.

Full textAbstract:
Computers and photography has had a long and complicated relationship throughout the years. As image processing and manipulating capabilities advanced on the computer front, photography re-birthed itself with digital cameras and digital imaging techniques. Development of interconnected social sharing networks like Instagram and Twitter feeds the photographers’/users’ thirst to show off their momentaneous “been there/seen that – capture the moment/share the moment” instincts. One other unlikely front emerged as an image processing power of the consumer electronics improved is “video game worlds” in which telematic travellers may shoot photographs in constructed fantasy worlds as if travelling in real life. While life-like graphics manufactured by the computers raise questions about authenticity and truthfulness of the image, the possible future of the photography as socially efficient visual knowledge is in constant flux. This article aims to reflect on today’s trends in in-game photography and tries to foresee how this emerging genre and its constructed realities will transpose the old with the new photographic data in the post-truth condition fostering for re-evaluation of photography truth-value.

Full textAbstract:
Purpose – The purpose of this paper is to explore how both producers and consumers of user-created music videos on YouTube communicate emotional information. Design/methodology/approach – In total, 150 filmic documents containing fan-generated versions of U2’s “Song for Someone” were purposively collected. The author used discourse analysis to understand the types of videos created, the communication of emotional information from both the producers and the consumers, the social construction of emotion in the filmic documents, and elements of intertextuality that represented emotion. Findings – Fans created videos containing cover versions, original versions of the song with new visual content, and tutorials about how to play the song. Producers of cover versions communicated emotional information, especially tenderness, through facial expression, their surroundings, and corresponding musical elements. Producers’ visual content expressed emotion through meaningful photographs and sad stories. Producers’ descriptions revealed emotion as well. Emotions were individually experienced and socially constructed. Consumers conveyed emotion through likes, dislikes, and expressive positive comments. Intertextuality communicated passion for U2 through tour references, paraphernalia displays, band photographs, imitating the band, and musical mashups. Practical implications – Information science can work towards a new generation of multimedia information retrieval systems that incorporate emotion in order to help users discover documents in meaningful ways that move beyond keyword and bibliographic searches. Originality/value – This is one of the earliest research papers in the area of emotional information retrieval (EmIR).

Introduction: Currently there are no portable solutions to robustly document and longitudinally monitor dynamically changing chronic skin conditions. This study set out to engineer and test a mobile-based 3D imaging solution for chronic skin diseases to enhance clinical workflow and patient care.Methods: SkinSpecs uses smartphone-captured videos of patients’ skin disease and renders 3D true-to-life models that were evaluated by Stanford Health Care dermatologists.Results: We utilized video input to accurately reconstruct interactive 3D models of 16 different skin conditions from 31 patients. Assessment of SkinSpecs 3D reconstruction is faster (p<0.05) compared to descriptive exam, standard photographs or original videos. Dermatologists maintained highest accuracy, confidence and satisfaction with 3D reconstruction. Dermatologist preferred SkinSpecs for documentation over other capture modalities. SkinSpecs was favorably used by dermatologists, with high satisfaction with resolution, breadth of visual information, time and ability to pick up incidental findings.Conclusion: We identified a proof-of-concept solution to objectively and robustly capture skin disease, with an office and home workflow that is acceptable to providers and patients. This fast, scalable method is deployable on smartphones and could be utilized to augment clinical decision making in the clinic and to empower patients at home.

Full textAbstract:
Social media continues to grow, permanently capturing our digital footprint in the form of texts, photographs, and videos, thereby reflecting our daily lives. Therefore, recent studies are increasingly recognising passively crowdsourced geotagged photographs retrieved from location-based social media as suitable data for quantitative mapping and assessment of cultural ecosystem service (CES) flow. In this study, we attempt to improve CES mapping from geotagged photographs by combining natural language processing, i.e., topic modelling and automated machine learning classification. Our study focuses on three main groups of CESs that are abundant in outdoor social media data: landscape watching, active outdoor recreation, and wildlife watching. Moreover, by means of a comparative viewshed analysis, we compare the geographic information system- and remote sensing-based landscape organisation metrics related to landscape coherence and colour harmony. We observed the spatial distribution of CESs in Estonia and confirmed that colour harmony indices are more strongly associated with landscape watching and outdoor recreation, while landscape coherence is more associated with wildlife watching. Both CES use and values of landscape organisation indices are land cover-specific. The suggested methodology can significantly improve the state-of-the-art with regard to CES mapping from geotagged photographs, and it is therefore particularly relevant for monitoring landscape sustainability.

We studied jungle cat distribution and their activity pattern in Koshi Tappu Wildlife Reserve (KTWR), Nepal. Photographs of the jungle cats obtained during camera trapping survey targeted to fishing cats in the winter season of two consecutive years (2016 and 2017) were used for this study. With an effort of 525 trap days from 69 stations, we obtained a total of 234 images/videos of jungle cats on 37 occasions from 15 stations. We recorded jungle cats distributed in the eastern buffer zone of the KTWR. All the jungle cat photographs were obtained in the night with peak activity within a couple of hours following the sunset. We suggest to carry out focused study specific to jungle cats to understand their distribution, status and diet.

Abstract. Rip currents (“rips”) are the leading cause of drowning on surf beaches worldwide. A major contributing factor is that many beachgoers are unable to identify rip currents. Previous research has attempted to quantify beachgoers' rip identification ability using photographs of rip currents without identifying whether this usefully translates into an ability to identify a rip current in situ at the beach. This study is the first to compare beachgoers ability to identify rip currents in photographs and in situ at a beach in New Zealand (Muriwai Beach) where a channel rip current was present. Only 22 % of respondents were able to identify the in situ rip current. The highest rates of success were for males (33 %), New Zealand residents (25 %), and local beach users (29 %). Of all respondents who were successful at identifying the rip current in situ, 62 % were active surfers/bodyboarders, and 28 % were active beach swimmers. Of the respondents who were able to identify a rip current in two photographs, only 34 % were able to translate this into a successful in situ rip identification, which suggests that the ability to identify rip currents by beachgoers is worse than reported by previous studies involving photographs. This study highlights the difficulty of successfully identifying a rip current in reality and that photographs are not necessarily a useful means of teaching individuals to identify rip currents. It advocates for the use of more immersive and realistic education strategies, such as the use of virtual reality headsets showing moving imagery (videos) of rip currents in order to improve rip identification ability.

Our objective was to determine whether pinnipeds could be detected through the forest canopy using thermal imagery. We used a UAV-mounted and a ground-mounted infrared camera to survey New Zealand fur seals (Arctocephalus forsteri) located in Ohau Stream and Point Kean coastal shrub forest on the east coast of New Zealand. These methods were compared to paired photographs and walk-through counts. Ground-mounted thermal images detected more seals than paired photographs during the cooler times of the day (morning and evening). In contrast, aerial thermal videos were successful in detecting fur seals in open areas, but were less successful in areas of high canopy cover (>80%). We discuss the advantages and limitations of thermal imaging for population sampling and provide some recommendations for future research.
